The current nd6 caching mechanism uses HWADDRHINT to cache destination index per pcb, but the corresponding neighbor cache entry is cached globally.

This means when we have 2 concurrent connections, the cache-index does not work often.

By adding a 'cached_neighbor_idx' to struct nd6_destination_cache_entry, this could be improved (the u8_t of this cache would not even increase the struct's size when hiding it between 'pmtu' and 'age').
